生物界中感受器成对出现,乃是一种相当普遍的现象。所谓成对感受器是指这样的一对感受器,它们或者由于本身结构的不同,或者由于彼此之间空间关系上的不同,使它们在同一刺激源的作用下作相反方向的反应变化。如果其中之一的脉冲发放增加,则另一个的脉冲发放便减少。本文讨论了这种成对感受器对生物系统调节品质的影响问题。首先,列举了若干生物学事实,说明生物系统体内稳态和姿势维持中的给定值可能是由成对感受器特性曲线的交点所决定。其次,假设误差消除过程满足下列方程I(d~2ε)/(dt~2)+μ(dε)/(dt)+κε=0此处ε——误差,I、μ和κ是常数。在此基本假设下,作者证明运用成对感受器原理可以改善调节品质,同时估计了一些定量指标。最后,作者证明运用同一原理还可减少元件变性对给定值的影响。
Receptors in the biological world appear in pairs, but it is a fairly common phenomenon. The so-called paired receptors refers to a pair of susceptors, which due to their different structures, or because of their spatial relationship between the different, so that they are under the same stimulus to the opposite direction of the reaction changes. If one of the pulses is increased, the other pulse is reduced. This article discusses the impact of this paired receptors on the regulation of biological systems. First, a number of biological facts are presented, indicating that the given values in the biological system for homeostasis and posture maintenance may be dictated by the intersection of the paired receptor characteristic curves. Second, suppose that the error cancellation process satisfies the following equation: I (d ~ 2ε) / (dt ~ 2) + μ (dε) / (dt) + κε = 0 where ε is the error, and I, μ and κ are constants. Under this basic assumption, the authors demonstrate that using the paired-susceptor principle can improve the quality of accommodation while estimating some quantitative indicators. Finally, the authors show that applying the same principle can also reduce the effects of component degeneration on a given value.
